Should I leave my husband...

I've been in a relationship with my husband for 8 years. We recently married over a year now and he constantly disappears to go out binge drinking for days on end with people who are no good at all. Then comes back when he wants. Always leaving me with the kids to take care of this may seem like a silly question to ask and please only comment seriously non judgments. I have left him before took a break for 6 months. I told him to leave today and hes gone now. Sometimes I feel like I'm being over dramatic I know hes never going to stop and I also know that no relationship or person is perfect.
